Patent CA-2340476-A1 (CA)
Title: A method for detecting, recording and deterring the tapping and excavating activities of woodpeckers
Inventor: BERGER ROBERT PAUL
IPC: A01M29/16
Filed: 2001-03-12
Abstract: An apparatus for deterring woodpeckers from tapping on and excavating within a utility pole or the like includes a housing having mounting flanges for direct attachment to the pole so as to receive vibrations therefrom. A  transducer is attached to the mounting wall so as to convert the vibrations preferentially over airborne sounds into signals. A circuit compares the vibrations with a long term average and emits an output in response to detection above a threshold, whereupon the outputs are counted and if the number within a predetermined time exceeds a preset minimum a sound transmitter is actuated for emitting a deterrent sound externally of the housing. A memory contains a plurality of separate audible deterrent sounds including some of the same species and some of predators which act as a deterrent to the woodpeckers and these are selected sequentially and transmitted after a delay to avoid habituation. The power source includes a solar cell charging a battery and to maintain battery power the circuit is arranged to partially power down between detecting periods, to prevent sound actuation at certain times of day and certain times of year and to issue deterrent sounds only once for every set time period.

Title: Detection and determination of the stages of coronary artery disease
Inventor: HOLVOET PAUL N
IPC: G01N33/68
Filed: 1999-08-31
Abstract: A method having clinically sufficient degree of diagnostic accuracy for detecting the presence of coronary artery disease in a human patient from the general population and for distinguishing between the stages of the disease in that patient is disclosed. The stages are, first, the non-acute stage, which is either asymptomatic coronary artery disease or stable angina, second, the acute stage known as unstable angina, and, third, the acute stage known as acute myocardial infarction. The diseased state (as opposed to the non-diseased state) is indicated by the clinically significant presence of a first marker in a sample from the patient. The presence of one of the two acute stages, unstable angina or acute myocardial infarction, is indicated by the clinically significant presence of a second marker in a sample from the patient. The presence of the more severe acute stage known as acute myocardial infarction is indicated by the clinically significant presence of a third marker in a sample from the patient. Preferably the first marker comprises OxLDL, the second marker comprises MDA-modified LDL, and the third marker is a troponin. Preferably the OxLDL and MDA-modified LDL are detected using monoclonal antibodies that can detect the presence of those markers in undiluted human plasma at concentrations as low as 0.02 milligrams/deciliter.

Abstract: An interoferometric fiber optic sensing system uses three optical fibers. A  sensing optical fiber is applied to a structure to be monitored to detect displacement or the like by changing its optical path length. A reference optical fiber has a fixed optical path length. An adjustable length optical fiber is controllably adjusted in its optical path length. The three optical fibers form optical paths whose light outputs are caused to interfere.  The adjustable length optical fiber is adjusted until an interference fringe appears. The quantity to be detected is derived from the maximum of the interference fringe. Several sensing optical fibers can be multiplexed; by staggering their optical path lengths, their interference fringes can be separated sufficiently to resolve them.
